Event notification uses the burst message mechanism to indicate that an alert has occurred. When event
notification is enabled and one or more of the selected alerts occurs, each active burst message will broadcast
HART Command 119 until the condition is acknowledged by a HART master.
Prerequisites
If you are using the Field Communicator, you must enable a burst message before you can configure event
notification.
Tip
Event notification affects only HART burst messages. Whether an alert is selected for event notification or not,
alert severity, alert status (active or inactive), fault timeout, and alert acknowledgment operate as normal.
Procedure
1. Enable event notification.
2. Select all desired alerts.
If one or more of the selected alerts occurs, each active burst message will broadcast HART Command
119 until the alert is acknowledged by a HART master.
3. Set Trigger Interval as desired.
Trigger Interval controls the delay before HART Command 119 s broadcast.
• Default: 0 seconds
• Range: 0.5 to 3600 seconds
Trigger Interval begins when the transmitter detects the alert condition. When Trigger Interval
expires:
• If the alert is still active, HART Command 119 is broadcast.
• If the alert is not active, no message is broadcast.
